ARKU Maschinenbau is headquartered in Baden-Baden and can look back on almost a century of company history. As a third-generation family business, the company's mechanical engineering operations are still carried out entirely in Germany.
All machines are manufactured at the Baden-Baden site and exported from there worldwide. This combination of local production and international orientation shapes both technological development and the company's commitment to quality and reliability.
A central focus is on sheet metal straightening machines for parts and coils. Especially after laser cutting, internal stresses arise in sheet metal parts, which can lead to warping. Straightening machines ensure that these stresses are balanced out and that the components are flat and dimensionally accurate again. In industrial manufacturing, this step is crucial for the reliable execution of downstream processes such as welding, bending, or assembly. The machines are designed for both individual parts and coils, thus covering a wide range of applications.
In addition to straightening, deburring technology is one of our core areas of expertise. After laser cutting, every sheet metal part has a burr. This burr not only impairs handling, but also function and further processing. Deburring machines reliably remove these burrs and simultaneously round the edges. This significantly increases product quality, both in terms of safety and functionality. In this context, deburring means more than just removing sharp edges. Targeted rounding prevents users from cutting themselves on sheet metal edges. At the same time, the parts are easier to assemble because there are no sharp transitions. This process also plays an important role for subsequent coatings, as paints and other surface coatings adhere much better to rounded edges.
The way in which the deburring machines can be adjusted is particularly innovative. Instead of defining numerous parameters manually, the system works with a few clear inputs. The operator specifies the type of part, for example, how pronounced the burr is, which material is being processed, and the material thickness. In addition, the desired result is defined, such as a strong or weak rounding or a specific surface finish. The machine adjusts itself automatically based on this information. This approach significantly reduces the effort required for commissioning and minimizes operating errors. Even less experienced specialists can quickly and safely operate the machine without having to undergo lengthy training. This increases efficiency in everyday production and ensures reproducible results.
The benefits of this technology are particularly evident in laser-cut parts. After laser cutting, burrs inevitably form along the cut edges. These must be removed in order to achieve consistent quality. The deburring machines are specially designed for these requirements and enable laser parts to be reworked economically and reliably. Not only are the burrs removed, but the edges are also specifically rounded, which increases the overall value of the component.
In addition to mechanical engineering, the company also offers contract straightening services. Customers can have their sheet metal parts straightened at both the Baden-Baden site and at international locations. Parts can be sent in or brought directly to a demo center. This service is particularly aimed at customers who do not operate their own straightening machine or who wish to have larger quantities processed externally. The demo centers also offer practical insights for interested parties who were unable to see all the details in operation at a trade fair. There, different applications and machine settings can be demonstrated under real conditions.
Complete manufacturing in Germany is an essential part of the company's strategy. It enables close integration of development, assembly, and quality assurance. At the same time, the machines are used worldwide, which places high demands on robustness and adaptability. Different materials, sheet thicknesses, and production conditions must be reliably mastered. This global orientation is also reflected in the further development of the machines. User feedback from various markets is continuously incorporated into new concepts. The aim is to develop machines that are easy to operate, enable stable processes, and ensure consistently high sheet metal quality.
Straightening and deburring are central steps in modern sheet metal processing. They determine whether components can be further processed without problems and whether the end products meet quality requirements. The combination of sheet metal straightening machines and deburring technology therefore forms an important basis for efficient and safe manufacturing processes. With a focus on automatic settings, maintenance-friendly designs, and reproducible results, it is clear that it is not just about individual machines, but about consistent process quality. This is precisely where the added value lies for users from various industries, from metal processing to industrial series production.
